Robust preconditioners for a new stabilized discretization of the poroelastic equations [PDF]
, 2020 In this paper, we present block preconditioners for a stabilized discretization of the poroelastic equations developed in [45]. The discretization is proved to be well-posed with respect to the physical and discretization parameters, and thus provides a ...

Using Dual Double Fuzzy Semi-Metric to Study the Convergence
Applied System Innovation, 2019 Convergence using dual double fuzzy semi-metric is studied in this paper. Two types of dual double fuzzy semi-metric are proposed in this paper, which are called the infimum type of dual double fuzzy semi-metric and the supremum type of dual double fuzzy
